CVE-2020-12061 (GCVE-0-2020-12061)

Vulnerability from cvelistv5 – Published: 2021-05-21 11:03 – Updated: 2024-08-04 11:48

Summary

An issue was discovered in Nitrokey FIDO U2F firmware through 1.1. Communication between the microcontroller and the secure element transmits credentials in plain. This allows an adversary to eavesdrop the communication and derive the secrets stored in the microcontroller. As a result, the attacker is able to arbitrarily manipulate the firmware of the microcontroller.

Severity

No CVSS data available.
